Following this procedure, future year D1RPM models will have similar nature to the Base Year 2015 AADTs trend. These values were compared to 2015 traffic count (year 2015 FTO data) and the difference (delta) and ratio were calculated. This delta and ratio were applied to the future year 2045 D1RPM model AADT values to correct the error in the model and to make sure growth rates are reasonable. The averaging from the two methods reduces the extremes that may be reached by one of the individual methods of difference method or ratio method. The similar method is used for the development of AADT for No-Build Alternative and General-Purpose Lane Widening/Capacity Improvement Alternative. The AADTs and peak hour volumes for No-Build and Build alternatives are given in APPENDIX B."
